' My invention relates to a spring end connection and particularly, though not exclusively, to 'a spring shackle construction for motorvehicles. r V

It is an Object of the invention to provide a springend connection havin'ghntifriction bearing means for sustaining; the normal loads between the frame and'spring, togetherwith means for sustaining side or what may be termed end thrust loads between those members:

It is a more specific-object to provide a spring end connection employing what may be termed radial load bearing antifriction bearing means for connecting a spring and frame together with antifriction bearing means for sustaining side or end thrustloa'ds between the frame and spring. 7

Briefly stated, in a preferred form shackle, I provide bearing means to be secured to a spring and a frame; Connecting shackle links serve to connect the spring and frame, and antifriction bearing members areinterposed between the shackle links and the bearing members carried by the spring and frame. To take up side, or what may be termed end thrust loads of the spring and frame, I employ means such as a ball or roller bearing device frame.

so that when assembled one set of antifriction bearing means may-take the normal or what may be termedradial thrust loads between the spring and frame, and another means which may be an antifriction bearing may take up the side or what may be termed axial or end thrusts between the spring and In the drawings which show, for illustrative purposes only, preferred forms of the invention Fig. l is a fragmentary end view of a spring and frame connected by shackles partly broken away for the purpose of illustrating inte rior construction;

Fig. 2 is a fragmentary, sectional view of a slightly modified form.

I have illustrated the invention in connection with shackle links-connecting the ends of an automobile frame and spring. It is to he observed that the invention is not confined to connecting the end of the frame and spring,

' Insaid drawings, 5'in'dicates apart ofa frame while 6 indicates a partof a spring to be connected to said frame. Bearing means such as a pin 7 may be secured to the frame 6 byany'suitable means or may be a drive fit in anleye of the frame. A similar'bea'r ing means such asthe pin 8 may be similarly secured in aneye in the spring 6. Shackle links 9-9 maybeemployedfor securing the spring and frame together. In the form shown these shackle links are provided with depressions .or cups10.10 at the ends into which the ends of the pins 78 maypro j ect; The shackle links 9. 9 may be definitely spaced apart by any suitable means such .means' of antifriction bearing members such as, the balls 13 -13. In the form shown these 7 balls are part of radial unithandlingbe'ar ings, the inner rings of which are on the ends of the pins 7' and 8. I do not wish to 'be con-. fined to a unit handling bearing, since the invention is of broader application, andany means of providing anantifriction bearing connection will suffice The antifriction bearing members such as 13 maybe arranged to sustain only the normal or what I term' the radial loads between the spring and frame. Unit handling bearings as rigidly secured to the pins such as 78 and'the shackle plates would sustain both radial and thrust loads, but'it is exceedingly diflicult to secure the bearing rings so as to properly take the end thrusts.

For the purpose of taking the side thrusts or. what I may term end thrust loads, I preferably employ one or more antifriction bearingssuch as balls 14 which mayengage any part fixed totheframe '5 and spring 6, for example, the-pins 7 and 8. These thrust to take the end thrusts or side thrusts bearin antifriction bearing members may be hel in suitable cages as 15. The ends of the cups may be closed by dust rings 16 as is usual. I

' In the modification shown in Fig. 2, I employ asinglethrnst member such as aLball 14 which may engage the pin 7' centrally so'bas 8.- tw the ri a d fr Whenmy roved spring end connection such as the shac le constructionillustrated-is in use, the antifriction bearing members'snch I as balls 13 sustain the spring an'd'frame and take thenorma-l or What I termradial loads,

that is, to a shackle construction has, been illustrated, I do notwish to be strictly limited to the constructions herein disclosed, since theinvention maybe otherwise embodied, and changesmaybe made within the pended claims,
